How do potatoes and sour radishes make chicken soup?

I have only heard of sour radish old duck soup. Who told you about this soup? It is estimated that he uses chickens instead of ducks at home! Also, his soup may be salty. With the addition of potatoes, it is easy to paste the pot and the soup is not refreshing. Drinking it will paste your mouth because potatoes contain starch. Let me tell you something about sour radish old duck soup! Cut the sour radish into strips one finger long and two fingers wide, put oil in the pot, add a few round red pickled peppers (if you don't like spicy, it's not very spicy, mainly because the color of fried radish makes the soup look a little red), stir-fry the radish 15-20 minutes on low heat to make it fragrant (be sure to use low heat, otherwise the sour radish will be tasteless, so you will eat it under pressure).
